SwiftKey, the most popular third-party keyboard on Android, is coming to iOS through a new note-taking app called SwiftKey Note. A leaked promotional image for the app has been leaked on Twitter today, but it’s not yet clear when it will be available to download from the App Store.

The image was published by @Evleaks, the ever-reliable source of leaked press photos. Unfortunately, there are no details to go with it, so it’s still unclear when the app will be available, or how much it’ll cost. But we do know it won’t be the same version of SwiftKey that Android users currently enjoy.

That’s because Apple doesn’t allow third-party keyboards in iOS, so while they can be integrated into individual apps, they cannot replace the default keyboard system-wide. Simply put, that means you’ll be able to use SwiftKey in SwiftKey Note, but not in other apps, like Messages or Mail.

SwiftKey could allow third-party developers to use the keyboard in their own apps, however, and that’s likely to be the closest we’ll get to a real keyboard replacement on iOS.

As you can see from the image above, the keyboard looks a lot like Apple’s own — the design hasn’t changed — but SwiftKey’s predictive typing features have been integrated into it. So as you’ll type, you’ll see a bar above the keyboard that suggests your next word — and the more you use it, the more useful it will get.
